IMPROVEMENT IN CIDERFNIILLS.

Specification forming part ot' Letters Patent No. 49,64 l, dated August 29, 1865.

To all 'whom it may concern:

Beit known that we,\'V. M. MCDOWELL and CHAs. E. BAEGHTEL, ot' Hagerstown, in the county ot' lV-ashington and State ot' Maryland, have invented a new and uselul lmprovement in Cider Mills; and we do hereby declare that the following is a full and exact description thereof', reference being had to the accompanying` drawings, and to the letters ot reference marked thereon.

In the construction ot' cider-mills it is ini portant to have the apples fed into the mill with ease and certainty, and to have the mill clear itself; and it is well known that the mill which comininutes the apples by a grating or rasping action will at't'ord a larger amount of cider, and of a better quality, than those mills which coarselyv crush or bruise the. apples in mass. In view of these facts we have invented a cider-mill working upon new principles--the combined action ot' a screw and series ot comininutingltecth.

Our Vinvention consists in a peculiar construction of screw-shaped grinder, in combination with comminuting-teeth In the accompanying drawings, Figure 1 is a side view ot' our machine. Fig. 2 is a top view otl the saine, the hopper and part of the shell heilig' removed. Fig. 3 shows the hopper and upper part ot' the shell detached from the mill.

ln the construction ot' our cider-inill any suitable frame may be ina-le, as seen atA, Figs. land 2. Upon this trame are arranged a driving-wheel, B, and a gear-wheel, (l, and also a balance-wheel, D. On thesaine shaft with thc wheels C and D is a screw-shaped cone or grinder, F. This grinder is emb 1aced .by a conical box, E, the upper halt' ot` which is removed in Fig. 2 and seen in Fig. 3, with the hopper ot' the mill. This screw-shaped grinder F is armed by a set of teeth or radial spikes, f, set spirally along the shaft of the grinder.

Two other or more sets or series of spikes are placed along the sides ofthe box or trough E, Fig. 2, and the threads ot' the screw-shaped grinder are cut through7 so as to revolve past these teeth. The teeth are so arranged as to catch and cut smaller and smaller the apples 0r pieces as they pass on through the mill. The action ot' our screw-cone is to throw the apples toward the center o fthe shaft, and thus save leverage in crushing the apples.

It will be observed that our screw-shaped cone acts reversely from the screw ot' an auger, and when in motion drives the apples regularly through the mill from the larger end ot the screw-cone to the smaller. In passing the whole length of the grinding-cone the apples must revolve three or four times around the shalt ot' the grinder, and in doing so must many times pass the series ofteeth e andf, and thus become tinely comminuted before'leaving the mill.

\Ve do not conline our invention to the precise arrangement ot' the details or the shape ot' the grinder, so long as the combined action ot' the screw and comminuting-teeth is secured.

More than two sets or series ot spikes may be employed along the box E, and other varia lions may be made without departingt'rom our invent-ion. l

le are aware that a screw has been used in a box provided with holes through which the juice escapes under the pressure otl the screw, but we believe our peculiar' arrangement ofthe screw, with notches in the thread to pass the teeth ot' the box E, is new and usetul. We are also aware that spikes have been used upon the box or shell and upon the cone or revolw ing center. Therefore we limit our claims to the new arrangement above described.

Having thus i'ully described our invention, what we claim, and desire to secure by Letters Patent ot' the United States, is-

The above-described arrangement 'of screw cone, provided with notches in the thread ot' the screw, and with the spikes f, in combination with the box E and teeth e, substantially in the manner and for the purposes set forth.
